it doesn't sound horrible, i still get a turkey sound because i don't have a dual set up but if you really what a good blow off valve, greddy rs or hks is the way to go, some will argue about turbosmart and tial. Running a dual set up is your best solution to a blow off valve. As far as lloks i like the forge bov as a nice bolt on upgrade
thans for the input man... i wanted to know cause i ordered one... i saw some vids on youtube with it on a ms3... it sounded ok... do they basically sound the same??
that was just the forge bov. Then I moved to the dual valve (i made a how to thread with pics like a year ago) then I went back to just bpv, then that broke went to another bpv then that broke now I am using a "ricer" ebay bov. I made a thread about the new bov, worked great and cost less than $50 with similar results to the forge, just a bit less swoosh. With hardpipes and an intake it probobly sounds the same as the forge. Nice thing about the cheapo bov is that it can be adjusted easily while the forge requires you to change the spring.
